CAR-DOOROPERATING MECHANISM.

To all whom 'it may concern:

Be it known that l, @nannies J. Rnnmx, of Pittsburg, in the county of.' .Xlleglnny and State of Pennsylvania, have invented rertain new and useful lmprovements in Car- Door-Operating Mechanism, ot which the following is a speciiicalion.

My invention relates to railway dampcars and more particularly, to a neuY and improved door operating and supporting mechanism for the dumping or discharge doors of cars ot this type.

ln the accompanying drawings, 'which illustrate applications oi.E my invention, l `ig ure l is an end view or a portion ot a car embodying my invention: Fig. 2 a part elevational and a part sectional view particularly showing the door operating mechanism, the section being taken on line 2-2 of Fig. 4; Fig. 3 a similar view, the section being taken on line 3 3 ot Fig, 4; Fig. 4 a part elevational vienv and a part longitudinal sectional view showing two doors and operating mechanism; Fig. a transverse sectional view showing a modilied torni 0f depending-member or racl: carried b v the door; and Fig. G a detail elevational View of a further modified torni of depend ing-member.

I have shown in v invention embodied in a dump-car of the type having a lloor formed almost entirely et hinged doors; these doors being arranged on each side of the car centervsill'and preferably hinged in series and operated from each corner of the car. As illustrated, l have shown only two doors` one door Q being an end door ot one row ot' doors on one side ot' the centersill 3, and 4 one of the intermediate doors of the same ron'. These doors are each hinged along the sides of the center-sill on. hinges 5 and are each provided with a (lepending-member G secured to and movable with the door. Member (3 is adapted to co operate with a rotatable and bodily movable shaft 7, which latter extends longitudinally of the ea and is supported in fixed slotted bearings 8 secured to or formed in the endsillv 9 and transverse members 10 ot the car nnderframe.

Member (i comprises an irregularly shaped member having a. curved portion 1l and a straight or' Hat portion t2. ,lis'illustratech this member is in the form oit an irregularrraek and is provided vWSit-h teeth 13 `Jformed on or secured to the curved portion Specification of Letters Patent.

and with teeth 14 formed on or secured to This dependingmember isadapted for engagement with and designed to cooperate with the rotatable shaft T, or with suitable engaging means mounted on the shaft, as for example, a gear-Wheel 15. The curved portion of the member (3 is preferably concentric With thel door-hinge 5, as shown in the forms of Figs. 2 and 5, but it may be of the curvature shown in Fig. G, that is, with a curved portion not concentric with the door-hinge.

The fiat portion of the depending member may be substantiallyT parallel with respect to the under face of the door or slightly inclined thereto.

Vl/'hen the door is in its closed position,

as shown in full lines in Fig. Q, the shaft 7 is directly under the 'lower portion 12 of member 6 With the gear-wheels 14 engaging ythe teeth of said portion, thus forming supporting means for maintaining the door in closed position. To open the door, shaft 7 is rotated by means of a suitable operating lever lo, or other suitablemeans. Owing to the rotation of shaft 7 together with its gear, it is apparent that the shaft will move or roll laterally in its fixed bearings during the travel of gear-Wheel 15 along the horizontal portion of the rack. When the end ofthe horizontal portion is reached the door and its depending-member will begin to descend and will, While gear 15 is meshing with the curved portion ofthe rack, drop into the position shown in dotted lines, Fig. 2.

To raise the door to a closed and locked position, ther rotation of the shaft is ref versed and said door is raised by means of the rotating gear meshing with the curved For the purpose of maintaining theI gear in mesh with the rack,

particularly during the period of change of travel from the curved portion to the straight portion, I provide means. on shaft 7, as a cam 17 operable in connection with a guide 18 to bodily move the shaft laterally in its bearings. After the door is inoved to a closed position a continued rotation of the shaft moves it 'under and along the flat portion of the rack. In the operation of opening or closing the door or doors the bodily.

movable shaft I rnoves horizontally in a plane parallel or substantially parallel With the floor of the car. To prevent the end discharge vdoors 2 A'from opening as Wide asthe doors 4, I provide hangers 19 arranged to engage said doors at the elevation desired, and, in addition thereto, I provide a clutch mechanism 20 acting in conjunction with gear-wheels 2l, which lat er differ slightly from the gear-wheels 15. p his clutch mech a nism 20 operates to prevent the turning oi' gear-wheel 2l after the doors i engage the hangers 1S), at the same time though shaft 7 l maintain the discharge doors in Lthe desired .inclined position during the operation of dumping. The depending-members are preferably provided with earing flanges 25 designed to bear upon flanges 26 of the gearwheels.

'lhe construction illustrated and described is one that is free of complicated parts and the moving parts of the door operating and supporting mechanism are of such a nature that they will not become clogged in use.

What I claim is:

l. A car comprising a hinged door, a rotatable and bodily movable shaft mounted to move in tixed bearings, a depending member carried by the door having teeth concentric with the door-hinge, and a gear on the shaft meshing with the teeth.

2. A ear comlirising a hinged door, a rotatable and bodily movable shaft mounted to move in fixed bearings, a depending member on the door having teeth concentric with the door-hinge and teeth parallel with the door, and a gear on the shaft meshing with the teeth.

)t car comprising` a hinged door provided with a depending member movable therewith, said member having an edge concentric with the door-hinge, and a rotatable and bodily movable shaft ha ving meansl (zo-acting with the depending member for closing' the door. i

4. A car comprisingra hinged door provided with a depending. member movable therewith, said member having a curved portion concentric with the door-hingel and a straight portion, and a rotatable shatlt provided with means engaging the curved portion for closing the door and eti-acting with the'straight portion for supporting ,the door.
